DIGITAL SIGNATURE
If this option is selected, you will be prompted to insert a
Digital Signature every time easyPDF Printer generates a PDF
file.
Click on the "Configure..." button to setup your Digital
Signatures.
What is Digital Signature
A digital signature identifies the person signing a document
pretty much same as the conventional handwritten signature does.
Unlike conventional signatures, however, a digital signature also
stores information about the person signing the document.
Signatures also help prevent unwanted changes to a PDF
document.
easyPDF Printer supports two kinds of signatures: visible and
invisible signatures. A visible signature appears both in the
document and the Signature tab. An invisible signature only appears
in the Signatures tab. A document is best signed only after you
have applied the final changes to it, so it doesn't have to be
altered anymore.
Select or Create a Digital ID
To apply Digital Signature into your PDF document, you must
first select the Digital ID that you would like to use to sign the
PDF file. If you do not have a Digital ID, you can create a new
one.
Create a new Digital ID
Click the "New" button to create a new self-signed
Digital ID. You will be the owner of this Digital ID, and
when you sign a PDF file using this ID, other people can verify
that your signature is valid by comparing it with your certificate
(you can send them your certificate before hand. See Export Certificate below for more information on how
to distribute your certificate).
Delete
Click [Del] to remove the Digital ID from the easyPDF Printer
Digital ID Bank. Click [View] to view the Digital ID details.
View
Click [View] to view the Digital ID details.
Import
Click to import a certificate from a file on disk.
A Certificate
A Certificate, which is issued by a certification authority, is
a confirmation of your identity and contains information used to
protect data or to establish secure network connections. A
certificate store is the system area where certificates are
kept.
File to Import
Specify the file you want to import. You will need password to
move forward.
Note: More than one certificate can be stored in a single file
in the following format:
- Personal Information Exchange - PKCS #12 (.PFX, .P12)
- Cryptographic Message Syntax Standard - PKCS #7 Certificates
(.P7B)
- Microsoft Serialized Certificate Store (.SST)
Export
You can export either your Certificate or your Digital ID.
Export Certificate
When you attach your digital signature to a PDF file, anyone who
needs to verify that you signed the document must have a copy of
your certificate. To export your certificate, click [Export] and
select [Certificate]. Please note that people can also obtain a
copy of your certificate by choosing to trust a document that you
have signed. However, physically giving them a *.cer file that they
can install and trust is a better practice.
Export Digital ID
You may need to export a copy of your Digital ID file (e.g.
giving someone else the power to sign documents on your behalf). To
export your Digital ID, click [Export] and select [Digital ID].
Please note that this file is encrypted and, and you must enter
your password to sign a document with this Digital ID.
Signature Details
You can change the signature details associated with a
particular PDF file such as "Reason for Signing", "Contact
Information," and "Location". This information will be included
with your signature.
Signature Location
If you would like your signature to appear as a graphic on the
first page of the PDF file, select the [Visible] checkbox. You can
then set the size of the graphic by changing the width and height
percentages. You can then click anywhere inside the "position box"
to choose the coordinates where the graphic should appear.
